Q.
A full wave rectifier circuit along with the input and output voltages is shown in the figure
The contribution to output voltage from diode $- 2\ $is
A) $A,C$
B) $B,D$
C) $B,\ C$
D) $A,\ D$
Explanation
(b) In the positive half cycle of input $ac$ signal diode $D_{1}$ is forward biased and $D_{2}$ is reverse biased so in the output voltage signal, $A$ and $C$ are due to $D_{1}$. In negative half cycle of input $ac$ signal $D_{2}$ conducts, hence output signals $B$ and $D$ are due to $D_{2}$
